but I tried to make the idea understandable.
You claim plasma = short circuit = resistance 0 Ohm.
Once a plasma is established it's impedance goes from being very high to very very low. In fact almost like a short circuit.
almostadverb: almost not quite; very nearly. "he almost knocked Georgina over" synonyms: nearly, just about, about, more or less, practically, virtually, all but, as good as, next to, close to, near, nigh on, not far from, not far off, to all intents and purposes, approaching, bordering on, verging on, nearing;
During the glow region the increase of current flow will create an avalanche effect in gas ionization that will transition the GDT into a virtually short circuit mode and current (dependent on the impedance of the voltage source) will pass between the two conductors. The voltage developed across the GDT with a short circuit condition is called the "Arc Voltage" VARC.
Your "short circuit" plasma generates no power.
inductor is NOT capacitor. In fact inductor is mostly presented as "inverse" of capacitor because their behaviour is "opposite". Capacitor tries to keep voltage constant and sources (or sinks) "any" current needed to do so until it runs out of energy. So when you short circuit the inductor it does nothing - the current flows in loop unchanged, inductor "is happy" and generates no voltage so wasting no power.
You may be right on this topic
I claim when (ideal) inductor
the following holds:I(t) = I(0) - t.Vf/L
What do you mean "may be"? Are you implying their is any doubt that Bourns do not know what they are talking about?
Stop right their, their is no ideal inductor here so that makes a nonsense of everything that follows.
The dimensions of that relationship do not add up. Time multiplied by voltage divided by inductance does not have the units of current.
Can you say in words what you mean by that, it sounds wrong. The dimensions of that relationship do not add up. Time multiplied by voltage divided by inductance does not have the units of current.
One could argue that no one ever chooses anything - that everything is pre-determined, and we're just playing out a script. And yet, we still use the word "choose", because it simplifies the discussion. That's what I chose to do in this case - simplify the discussion. But then, I think you knew that.
sorry to diverge from the inductance debate to bring the water analogy back into it; this is how i understand the "diode protection" happening;imagine two pipes connected to a water source (5m up from the ground) - one runs off into a basin 4m up from the ground, while another runs off straight onto the ground.a trickle would probably reach the basin, but most of the water would flow through the pipe down to the ground.am i correct in understanding this analogy of electricity/water flow ?
The diode must be able to handle the initial current at turnoff, which equals the steady-state current flowing through the inductor when the switch is closed. In addition, the voltage ratingfor the diode needs to handle the swing between positive- and negative-voltage levels. A rule of thumb is to select a diode rated for at least the amount of current the inductor coil drawsand at least twice the voltage rating of the operating voltage of the load. For many applications, especially those found in industrial applications that have many output channels per IOcard, this diode is often physically quite large and adds significant extra cost to the BOM.The other major disadvantage of the simple freewheel diode approach is that it lengthens the decay of current through the inductor. As explained in "Coil Suppression Can Reduce RelayLife," this slow decay of current can create problems such as "sticking" between relay contacts. For applications where the current must decay quicker, an alternative solution is to use aZener diode as shown in Figure 4, which gives a faster current ramp rather than an exponential decay. When the switch opens, the current is shunted through the general-purpose diodeand Zener diode path, maintaining a voltage equal to the Zener voltage (plus forward diode drop) until the inductor energy is dissipated.
This diode shunt provides maximum protection to the solid state switch,but may have very adverse effects on the switching capability of therelay. It is important to realize that the net force available to cause thearmature to open is the difference between the magnetic restrainingforces and the spring opening forces, that each of these is varying in amanner to cause the net force to vary both with time and armatureposition. It is this net force which gives rise to the armature systemvelocity and energy of momentum as it attempts to effect armature andcontact spring transfer.A slowly decaying magnetic flux (the slowest is experienced with a simplediode shunt across the coil) means the least net force integral availableto accelerate the armature open. In fact, rapid loss of the opening forcessupplied by stiff NO contact springs, coupled with slowly decayingmagnetic forces, can actually cause a period of net force reversal wherethe armature velocity is slowed, stopped, or even momentarilyreversed until the flux further decays, finally permitting available spring"return" forces to cause transfer to continue....The more rapidly the coil current decays, the less the magnetic holdback, and thus the greater the armature momentum and contact stick"break-ability."Obviously, this is optimized when no suppression is used. However,near optimum decay rate can be obtained by using a Zener diode inseries with a general purpose diode. When the coil source is interrupted,the coil current is shunted through this series arrangement, maintaininga voltage equal to the Zener voltage (plus forward diode drop) until thecoil energy is dissipated. This is illustrated in Fig. 3.The Zener voltage value is chosen to limit the coil switch voltage to alevel acceptable to the switch rating. This affords the best compromiseboth to coil switch protection and relay switching performance, and shouldbe employed to assure maximum relay performance and reliability whileproviding protection to the control circuit from coil induced voltages.
The best solution is to put a diode across the inductor, as shown at left. The diode must be able to handle the initial diode current, which equals the steady current that had been flowing through the inductor; something like a 1N4004 is fine for many cases.When the switch is on, the diode is back-biased (from the dc drop across the inductor's winding resistance).At turn-off the diode goes into conduction, putting the switch terminal a diode drop above the positive supply voltage.The only disadvantage of this protection circuit is that it lengthens the decay of current through the inductor, since the rate of change of inductor current is proportional to the voltage across it.For applications where the current must decay quickly (high-speed impact printers, high-speed relays, etc.), it may be better to put a resistor across the inductor, choosing its value so that Vsupply + IR is less than the maximum allowed voltage across the switch. For fastest decay with a given maximum voltage, a zener could be used instead, giving a ramp-down of current rather than an exponential decay.Source: "The Art of Electronics" by Horowitz and Hill, Cambridge University Press, copyright 1980, ISBN 0-521-23151-5
You started it.
...science is just fitting patterns that everyone can recognise and atheism is just the other extreme after so many thousand years of organised religion both are as unlikely as each other but anyway I digress
and you are misunderstanding atheism as an "extreme opposite" of religion - you're probably thinking of anti-theism.

I was talking about atheism as the idea that the universe just happened. The Big Bang proposes that everything sprang into existence in an instant (quantum fluctuation) for no reason, its all just dumb energy.
Think about that and try to conceive an idea as unlikely. It is in fact just as unlikely as And god said let there be light
